Need help deciphering hp-28s program - mbrethen - 02-01-2015 06:06 AM
I thought I'd try "411 for the HP 28S", labeled a "Directory Assistance System" written by Tom Affinito in 1988. The 'BUILD' command follows:
Code:
BUILD CREATE A NEW WORKSPACE
'name' :
<< HOME ->411 DUP O->S "UTIL" + -> n n.s
<< IF VARS n POS THEN "NAME IN USE" 1 DISP BOOP
ELSE 'WK.LS' DUP EVAL n + SWAP STO
"<>" + STR-> n STO
UTIL
n.s DUP S->N CRDIR STR->
WORK CRDIR
<< WON >> SWON STO
{} SU.LS STO
MAIN
END
>>
>>I get a "Too Few Arguments" error on "<>", line 4. Does anyone know what the symbol "<>" represents?

Update: I stumbled upon another source for this program. Line 4 is replaced by
Code:
"<<UTIL " n.s + " WORK SWON>>" + STR-> n STOAll is well.
